The fouling communities that develop in coastal
waters are rather well studied; however, deepsea foul
ings, including those in communities that develop in
the bathyal, abyssal, and ultraabyssal zones, have
been studied extremely poorly. It is possible to explain
the poor study of deepsea fauna by technical prob
lems, the high cost of deepwater research, and other
reasons. One of these is the rare occurrence of sub
strates of an anthropogenic origin in the deep sea rela
tive to their occurrence in the littoral and sublittoral
zones. Another reason is the nature of artificial sub
strates (sunken wrecks, their fragments, and other
technical structures) that create additional problems
for their research related to the tangling and damage of
fishing instruments, deepsea vehicles, etc. In this
relation it is not surprising that publications devoted to
deepsea foulings are few and that they mostly con
cern foulings of deepsea cables [6– 8, 10–12, 15, 17].
In the study of the foulings of sunken ships, sampling
is possible only with complex deepsea vehicles,
including manned ones, or, at least, real time ROVs.
The barnacles (Cirripedia and Thoracica) are one
of the major groups of animals found in marine foul
ings. With the help of the author, an annotated list of
species of this group in fouling communities on sub
strates of an anthropogenic origin was prepared , in
which, along with species inhabiting the coastal zone
and pelagial species, the species occurring in deepsea
fouling were presented. Further study of collections of
deepsea barnacles collected in Russian expeditions to
the North Atlantic and adjacent areas of the Arctic
Ocean enabled us to find two barnacle species that
were formerly unknown in deepsea foulings. We sub
mitted descriptions of these species and data concern
ing their finding. The systematic position of the con
sidered species was specified according to Newman

—The study of deepsea barnacles collected by Russian expeditions to the North Atlantic and adja
cent areas of the Arctic Ocean revealed two barnacles species in the foulings of sunken vessels, viz.,
(Hoek, 1883) and
(G.O. Sars, 1877) that were not previously known in
deepsea foulings. Descriptions of these species are given. The role of barnacles in deepsea fouling commu
nities is discussed.
